R&D pipe(s) question

[yamaboy2000]

I have recently acquired both an R&D dry and R&D wet pipe, I believe I have the water hook-up instructions for the dry chamber but I'm not to sure about the wet pipe installation..Also it appears to me that there is absolutely NO difference between the two chambers other than the dry simply has an outer jacket but they both have nozzels with #80 jets in there chambers that will inject water directly with the exhaust gases, so I really can't see where there would be ANY performance difference between the two other than lower under hood temps...Can anyone explain a difference other than what I am seeing and understanding??:banghead:

For the wet pipe install and cooling routing, PM Beachjunkie. He's been down the road with this pipe.

how do i get in contact with beachjunkie, i did a name search with no luck...How come no one knows crap about these pipes?? R&D can't even get me a copy of the tuning/installation instructions and supposedly only 1 person(whom is NEVER there) is the only person who knows or understands this exhaust system..I would have never guessed there was such a lack of knowledge around this pipe...
